I found these papaya bites in the small animal section at Petco. They don't contain any of the harmful ingredients that some of the hermit crab foods contain. The only ingredients listed are papaya and I think some coloring. They are dehydrated and come in a zipper seal bag. There were also some dried friut mixes in the same brand as well. Whe I looked at the ingredients, I fully expected to see all sorts of oreservatives and CS and E....I was totaly surprised at how natural they are...there is some sort of food coloring in them...some pieces are red, purple, yellow, and green. My crabs seem to like them. Thanks to you guys, I'm trying more natural foods and finding it to be easy and inexpensive. I am afraid however of not giving them well balanced diet. Does anyone have a rule of thumb for making mixed batches of crabby food...like one source of calcium, a source of protein etc.? I tried putting a leftover corb cob in the crabarium last night...my two little guys ran from it...guess it was a little intimidating. I'm going to check out a local sea shell shop today and I will report back to the group if they have some good crabby shells. Someone told me that they even sell hermit crabs...will have to check that out!
